The A9P was originally installed in 1988-92 Mustangs with automatic transmissions. The "A9P" designation can be found on the tongue portion of the computer. We can rebuild any 1988-93 computer, regardless of the designation.

If you do not have a computer to rebuild, we have used, OEM A9P computers that you can purchase. The total cost is $575 and we can usually ship it within 5 business days. Cores are getting hard to come by, so we prefer to rebuild your existing computer if you have one. One-year warranty is valid on computers that you purchase from us.
